Description

Technical Field

[0001] This utility model relates to the field of ceramic production technology, specifically to a firing device for producing wear-resistant ceramics. Background Technology

[0002] Wear-resistant ceramics are special corundum ceramics made from AL2O3 as the main raw material and rare metal oxides as flux, and fired at a high temperature of 1700 degrees Celsius. They are then combined with special rubber and high-strength organic / inorganic adhesives. Due to their excellent wear resistance, wear-resistant ceramics are widely used in many industrial fields.

[0003] In the production process of wear-resistant ceramics, the firing process is a critical step, directly affecting the performance and quality of the ceramics. The basic characteristics of wear-resistant ceramics are mainly reflected in their high hardness, wear resistance, and corrosion resistance. These characteristics enable wear-resistant ceramics to maintain stable performance in extreme environments. For example, in the aerospace field, wear-resistant ceramics are widely used in engine parts and shell materials. Their high temperature and high pressure resistance ensures the reliability of aircraft. At the same time, due to their excellent wear resistance, the automotive industry also widely uses wear-resistant ceramics as materials for key components to improve vehicle service life and safety. With the continuous advancement of technology, the requirements for wear-resistant ceramics will become increasingly stringent.

[0004] Traditional firing equipment suffers from inaccurate temperature control, which can lead to localized overheating or underheating during the firing process. Localized overheating can cause abnormal grain growth in ceramic materials, while underheating can result in insufficient densification, leading to porosity and cracks, thus affecting the strength and toughness of wear-resistant ceramics. Furthermore, poor heating uniformity can cause uneven sintering in different parts of the wear-resistant ceramic green body, resulting in differences in the product's hardness, wear resistance, and impact resistance at different locations. Inaccurate temperature control and poor heating uniformity can also lead to significant differences in the performance of different batches of products. Therefore, a firing device for the production of wear-resistant ceramics is needed to improve upon these problems. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0026] For examples, please refer to Figures 1-4 This utility model provides a technical solution:

[0027] A firing apparatus for producing wear-resistant ceramics includes a main body 1, and a rotating component 2 is disposed inside the main body 1.

[0028] In this embodiment, as Figure 1 , Figure 2 and Figure 3As shown, the main body 1 includes a base plate 101. A furnace body 102 is fixedly connected to the top of the base plate 101, and a PID controller 103 is fixedly connected to the side of the furnace body 102. A temperature sensor 105 and a heating wire 106 are fixedly connected inside the furnace body 102. The rotating assembly 2 includes a support plate 201. A drive motor 202 is mounted on the top of the support plate 201. A rotating wheel 203 is fixedly connected to the output end of the drive motor 202. A transmission wheel 204 is meshed with the side of the rotating wheel 203. A rotating shaft 205 is fixedly connected inside the transmission wheel 204. By using several temperature sensors 105 installed inside the furnace body 102, the temperature distribution of the furnace body 102 can be monitored in real time. By using the PID controller 103, the current of the heating wire 106 can be precisely controlled according to the preset firing process temperature curve and the temperature data transmitted by the temperature sensors 105, so as to ensure that the temperature of the furnace body 102 changes according to the set process requirements.

[0029] The PID controller 103 has a display screen 104 fixedly connected to its side. The furnace body 102 has a sealed door 111 on its side. Several temperature sensors 105 and heating wires 106 are provided. The bottom plate 101 is a cylindrical sealed structure. The top of the rotating shaft 205 is fixedly connected to a placement plate 206, which is disc-shaped. The top of the support plate 201 is fixedly connected to a bearing seat 207. The rotating shaft 205 extends into the interior of the bearing seat 207. The placement plate 206 is made of ceramic and its surface is coated with silicone resin. The starting of the drive motor 202 causes the rotating wheel 203 and the transmission wheel 204 to perform gear transmission, thereby driving the rotating shaft 205 to rotate. This allows the wear-resistant ceramic blank to rotate evenly during the firing process, further improving the uniformity of heating. This ensures that the wear-resistant ceramic blank is heated evenly during the firing process, avoiding inconsistent product performance caused by local temperature differences.

[0030] In this embodiment, as Figure 1 and Figure 4 As shown, a top plate 107 is fixedly connected to the top of the furnace body 102. An exhaust fan 110 is installed on the top of the top plate 107. A gas supply pipe 108 is fixedly connected to the top of the top plate 107. A gas pump 109 is installed at the bottom of the gas supply pipe 108. The gas supply pipe 108 supplies nitrogen gas. Nitrogen gas is introduced into the firing chamber furnace body 102 through the gas supply pipe 108 to protect the wear-resistant ceramic blank during the firing process and prevent it from undergoing adverse reactions such as oxidation at high temperatures. The exhaust fan 110 can discharge the gas inside the furnace body 102, thereby discharging the waste gas generated during the firing process, maintaining a stable atmosphere in the furnace body 102, and thus meeting the firing atmosphere requirements of different wear-resistant ceramic materials, improving the performance and quality of the products.

[0031] The working process of this utility model is as follows: When the firing device for producing wear-resistant ceramics designed in this scheme is in operation, the wear-resistant ceramic blank to be fired is placed on the placement plate 206, the sealing door 111 is closed, nitrogen gas is introduced into the furnace body 102 by the gas pump 109 and the gas supply pipe 108, and the air is discharged by the exhaust fan 110. Then, the PID controller 103 is started to control the temperature sensor 105 and the heating wire 106 to monitor the temperature inside the furnace body 102 and control the heating state inside the furnace body 102, and according to the preset... The firing process temperature curve heats and fires the wear-resistant ceramic blank. During the firing process, the start of the drive motor 202 causes the rotating wheel 203 and the transmission wheel 204 to perform gear transmission, which in turn drives the rotating shaft 205 to rotate, so that the wear-resistant ceramic blank on the placement plate 206 rotates evenly during the firing process. At the same time, the temperature sensor 105 monitors and precisely controls the temperature of the furnace body 102 in real time to ensure the smooth progress of the firing process. During the firing process, the heating wire 106 is energized and heats up to heat the wear-resistant ceramic blank inside the furnace body 102.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
